Racing Chassis '60-63 Corvair Sectioning and Widening Front Suspension

When you use the suspension parts on a narrow frame the track is to narrow.Like a '50's Indy car.

To get the wheels back out there I thought of this.

Section the upper a arm and the lower control arm.

Add material and weld up.

Then you would do the same to coil spring buckets.

How does that sound?

Sounds like you have no clue at all what you are talking about! The EM front and rear cross members are a unit, if you bolted them onto a tube chassis, the front and rear wheel track would be the same width as they are bolted onto a car.

Thanks

Guess we left out a step.

Section the front cross member.

Cut out a fair size chunk of the hat section.

Only keeping the necessary part to bolt suspension to.

NOW put them on each side of new solo seat racing chassis.

It is TOO NARROW.

Now continue with what I said in first post.

So if I get this correct, you are going to shorten the cross member, then lengthen the A-Arms, to get right back where you started! drinking smiley

'Make a drawing of what you are talking about'

Aww! Can't we talk bench racing?

'you are going to shorten the cross member, then lengthen the A-Arms'

YES!

This is what you end up with if you do not widen (lengthen) them.

That is 50's early 60's Indy FRONT ENGINE car.

Early 60's they changed over to mid engine with 'outrigger' double a arms or wishbones mostly.Widened the track of the car.

'going to shorten the cross member'

NO.

Cut out and remove part of the crossmember.

DO NOT put the two ends back together.

DO hang them on the side of a homebuilt tubular frame.

THEN to widen the track back up to stock width EXTEND the suspension.

Here is simple drawing of a arm.

First you section it.

Then ADD in the center of it.

Where the red lines are.

Hope that helps.

Here is picture of a tube frame.

The sides are straight like a sprint car.

It is a simple '4 tube' frame.

Build the mid engine Corvair single seat open wheeler using that kind of frame.

Changing the length of the A-Arms will change the suspension geometry and handling characteristics. Most likely in a bad way, unless you understand suspension geometry and chassis dynamics enough to prevent ruining it.

You can bench race all you want but the reality is a race car tube frame is built with components that are compatible with the material and thickness of the tubing. It is designed with using the lightest weights possible. Putting the heavy Corvair components on that tube frame will tear it apart. Stock parts can only be lightened so much that is why fabricating or purchasing new light parts is best and also allows one to improve geometry as needed.

at one time I had a narrowed Corvair front suspension in an MG-TD. It worked great but the center section was removed and welded back together. I makes no sense to alter the a-arms and destroy suspension geometry. An MG rack and pinion was also used with the Corvair unit. The car also used a narrowed Corvette rear but that's a whole other story

Thank you for all the responses!

Okay.

Sectioning the suspension components is a bad idea.

Best to build a 'mule' first.

Simple ladder frame with front and rear suspension with complete and intact crossmembers.

It was mistake to 'get cute' with suspension parts first time around.

If your building a racing chassis, there are a lot of better suspension designs to start with. Not being mean, but you really need to do more research on suspension design before you start cutting.
